In this tutorial, we explain how to use the ‘Target’ tab in FIR Designer, the second step in the FIR Designer workflow for designing custom DSP and FIR filters for loudspeakers and audio systems.
The target tab is used to define the desired magnitude and phase response for your loudspeaker or DSP-enabled audio device before FIR filter, or mixed IIR+FIR filter design.
The creation of a custom target response is demonstrated through the selection & combinination of up to four contributing components:
- Curve – Define a magnitude or EQ profile using slope segments and a base shelf.
- Magnitude – Create a magnitude profile based on common filter prototypes. (Choose from parametric and shelf filters, low-pass and high-pass crossover filters, and unique Keel-Horbach crossover responses.)
- Phase – Create a phase profile using common first-order and second-order all-pass filters or our unique ‘fourth-order’ parametric phase filter.
- File – Load an impulse response or transfer function measurement to incorporate into the target response (for example, when matching to the response of another loudspeaker). See all supported file formats.
Saving target presets for reuse in other projects and exporting the magnitude response as a Smaart® target file are also covered.
This video is the second in a new tutorial series, with each video focused on a single FIR Designer workflow tab. These new tutorials will gradually replace several older tutorial videos, ensuring coverage of the full feature set available in current FIR Designer versions.
